Our Easy-Grip Sleeve gives anyone a sure way to drink from the chamber with a nipple for feeding your sweet babies as they need more milk, formula, water or juice. Or use this beautiful blue and white sleeve to give you a good grip while pumping or to later allow you to sip your drink of choice - coffee, water or wine - with a temperature sleeve for your hands. Using glass bottles like Dr. Brown's? This silicone sleeve gives you protection from shattered glass, in addition to the grip and insulation your baby needs. Made from food-grade silicone and textured for gripping and style. Slip it onto the Inner Chamber of our Chiller or favorite glass baby bottle and and you're all set!
